Applicatio:

Adenina (Synonyma: 6-Aminopurina; Vitaminum B4, CAS: 73-24-5), purinus est unus ex quattuor nucleobasibus in acido nucleico DNA.Adenine etiam in biochemistria quae in respiratione cellulosa, forma ATP et cofactorum (NAD et FAD) et synthesin interdum (n) magnas partes agit.Praeter haec, in productione nucleotidum acida nucleica adhibita est.Ad adenosinum, ATP, ADP producendum, medicamentum anti-auxilia et vitaminum B4 et incrementum hormonum 6-benzyl adeninum plantandum, etiam in investigationis pharmaceuticae et biochemicae adhibita.In praesens, cibus domesticus et Administration medicamentis adhuc utitur nomine Vitaminum B4 ad interpositione, et multa officinae pharmaceuticae domesticae sub nomine Vitaminum B4 tabulas adeninas efficiunt.Adeninum nucleobasum purinum est.Est pars DNA, RNA.Adenine est etiam elementum cofactorum (NAD, FAD) et moleculis significans (cAMP).Basis nitrogenosa in DNA et RNA inventa est.Est etiam quaedam coenzyma et coniuncta cum riboso saccharo nucleosida adenosina inventa in AMP, ADP, ATP.Adenine anuli purinum structuram habet.Una est e maioribus basium componentium ofnucleotidum et acida nucleica DNA et RNA.
